Three fatal cases of encephalitis were reported in 2015 which had occurred between 2011 and 2013 in Germany and were associated with a novel Bornavirus species. A further human case, also a fatal encephalitis, due to the same novel Bornvirus was reported in 2018. This risk assessment was carried out to determine the level of risk to the UK population.
